Abstract

Vorrichtung bzw. Verfahren zur Darstellung von computermodellierten Objekten, die aus einer Vielzahl von aneinandergrenzenden Polygonflächen zusammengesetzt sind, wobei der Bildeindruck in den Eckpunkten der Polygonflächen entsprechend einem lokalen Beleuchtungsmodell berechnet wird, wohingegen der Bildeindruck der restlichen Rasterelemente entsprechend dem Gouraud-Schattierungsverfahren interpoliert wird und zur Simulation einer Oberflächenstruktur für jedes Rasterelement zusätzlich ein Farb- bzw. Helligkeitswert berechnet wird, der den Einfluß der Oberflächenstruktur auf den Bildeindruck berücksichtigt, ohne in jedem Rasterelement aufwendig das lokale Beleuchtungsmodell berechnen zu müssen.

Figure 00000001
Device or method for displaying computer-modeled objects which are composed of a plurality of adjoining polygon surfaces, the image impression in the corner points of the polygon surfaces being calculated in accordance with a local lighting model, whereas the image impression of the remaining raster elements is interpolated in accordance with the Gouraud shading method and for Simulation of a surface structure additionally calculates a color or brightness value for each raster element, which takes into account the influence of the surface structure on the image impression, without having to laboriously calculate the local lighting model in each raster element.
